Question: 1 / 400

In primary molars, radiographic bony changes from an infection are initially seen in which area?

Apical Region

Furcation Area

B Furcation Area. In primary molars, the furcation area is the first place where radiographic bony changes from an infection are seen. This is because this area is the point where the roots of the tooth meet, making it more susceptible to infection and damage. The apical region (A) and root canal (D) may also show some changes, but they typically occur later on in the infection process. The crown of the tooth (C) is not a common area for bony changes to occur in an infection.
